Voice cabling is the wiring of a building which enables basic telecommunications systems including land-based phone lines, modems, or analog lines. These copper or fiber cables carry data across long distances and are increasingly designed to transmit greater amounts of data at higher speeds.

Function
Voice cabling is the primary step in installing a land-based phone line, modem or analog line. This wiring is essential for telephone cabling as well as for other network applications that allow for spoken communication or other voice services over long distances. Voice cabling uses voice-grade wire and standard telephone jacks to connect telephone landlines to local communication systems.

Types

o   There are several types of voice cabling, and newer varieties have been developed in recent years to comply with national and global communication technology standards.
o   Category 1 cabling was a common type of land-line cable that is no longer recognized by the Telecommunication Industry Association. It was used for basic telephone communication and doorbell wiring.
o   Category 3 cable is a copper, unshielded twisted pair cable created to transmit up to 10 mb of data per second, and is the current voice cabling standard.]
o   Category 5 cabling is another commonly used unshielded twisted pair cable designed for high signal reception that allows for far-end communication.
